| Season | Club | Days | Running total | How this season is known |
|---|---|---|---|---|
| 2013 | San Diego Padres | 22 | 0.022 | From transactions |
| 2014 | Pittsburgh Pirates | 11 | 0.033 | From transactions |
| 2015 | Pittsburgh Pirates | 64 | 0.097 | From transactions |
| 2016 | Tampa Bay Rays | 104 | 1.029 | From transactions |
| 2017 | Oakland Athletics | 24 | 1.053 | From transactions |
172 days credit a full year, so a season adds at most 1.000 no matter how long a player is on a roster. 3.000 years reaches salary arbitration and 6.000 reaches free agency —
what every threshold unlocks.
